    I have already checked for codes and it gave me #55 (no malfunction). Its a new tbi unit so Im assuming the whistling is because I cleaned the EGR port and the pipe on the mixture pre-heater is making it whistle. Ita at a shop (that I work at) and Ive gotten it to run. However, it is extremely rough. The surging has gone done quote a lot, it idle and runs, but is very, vey rough. I replaced the 2 injectors and we tried messing with some vacuum lines but its stop really rough. Maybe ignition timing?
  2. Josh_Path2346
    And the whistling noise is coking from inside / underneath the throttle body. However I have just swapped tbi units and its still whistling so its not a gasket. Im thinking the mixture heater pipe is causing the EGR tube to make a whistling noise

    Im pretty sure it isnt timing because itll run for just a few seconds then ill choke itself out while it sputters to a stop. My timing belt was serviced before I bought this truck but the sticker has been wiped clean so I cant see the mileage anymore.

    What happened, did you get it fixed? Im having a similar problem
  5. Josh_Path2346
    I have an '88 Pathfinder 3.0 v6 that has been giving me trouble for the past 5 months. I just replaced the throttle body (entire unit, sensors too) and now I have a whole new problem. It used to surge up and down erratically, but now it wont even stay running. I think its flooding itself out. It also has a high pitched whistle (no, I dont have a vacuum leak. Ive checked) and will run fine for a few seconds then stumble and die. Ive been struggling for months with this problem, can someone please help me?
  6. Josh_Path2346
    Tried searching for a vacuum leak but nothing worked. Sprayed everywhere with starting fluid and nothing happened. Gonna replace the tbi unit
  7. Josh_Path2346
    How did cleaning your tbi go? Did it start working again or give you any problems? I rebuilt mine and now its wheezing and whistling and revving up and down
  8. Josh_Path2346
    Thanks, Ill give it a try. Anything else I could test while Im at it? Im pretty close to just buying a new Throttle Body unit
  9. Josh_Path2346
    Well, it does have suction, but I can put my hand over it and it doesnt change anything. I have tirelessly searched this and other forums for a problem like mine and havent found an answer. Im close to just sending it somewhere to get fixed
  10. Josh_Path2346
    I searched for vacuum leaks and couldn't find anything. Sprayed every hose on both ends and the engine didnt react. After a few minutes amd a couple starts I ended up vapor-locking it and gave up. Got any other ideas?
  11. Josh_Path2346
    I cant hear it making any sucking noise, because its whistling too loud. Ive got a new can of ether so tomorrow night Ill give it a shot. Any ideas where to start? Likely areas?
  12. Josh_Path2346
    I have checked my computer and got a code 55 (no malfunction) I could take the throttlebody off and try the throttle plate screws. It didnt close all the way when I had it off replacing the gaskets. However, there it literally no suction coming from the throttlebody. Im going to test for vacuum leaks tonight
  13. Josh_Path2346
    I've replaced my gaskets and made sure everything worked and I still have the revving up and down problem. (Approximately 2,000-2500) Can anyone help me? I have no codes but am pretty sure its a vacuum leak. I just don't know where
  14. Josh_Path2346
    Ive replaced the MAF sensor so that isnt it
  15. Josh_Path2346
    My 1988 Pathfinder VG30i gave me a 55 (no malfunction) today, however there is a vacuum leak that might be causing the idle do rev up and down (approximately 1700-2500). I chased it down to behind the throttle body. Should I take it off and try to tighten it down again or look for something else?
